FIRE-HYDHANT DFAlN.

Specioation of Letters Patent.

Patented July 3. 1966.

Application filed March l?, 1905. Serial No. 250,531.

To all whom t may concern:

Be it known that I, GEORGE J. WILLIAMS, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State otPennsylvania, have invented certain new and useful Improvements in Fire-Hydrant Drains, of which the following is a speciication.

My invention relates to certain new and useful improvements infire-hydrants. and has for its object to provide means for carrying oitany waste water accumuiated therein after the closing of the valve and,furthermore, in providing means wherebv the same may be prevented fromfreezing through the introduction of steam.

My device for effecting the above consists, broadly, in a receptacleinto which the water above the valve drains and from which it is drawnby a suitable means, such as a handpum inclosed in the casing of thehydrant, suita le connection being provided With said receptacle for theintroduction of steam from a portable boiler, such as oi' a lire-engine.

In the drawings forming a part of the specication, and in which likenumerals of reference designate corresponding parts throughout theseveral views, Figure 1 is a vertical section in elevation of my deviceattached to a hydrant, which latter may be of any of the Well-knownforms. Fig. 2 is an elevation of the above-ground portion of the hydrantWith the pump-box front removed, and Fig. 3 is a detail elevation oftheump.

Reference-numeral 1 esignates the barrel of the hydrant, 2 thevalve-casing, and 3 the seat for the valve 4, having the usual oerating-rod 5 threaded in cap 6. The sai barrel is provided With theusual outlets 7, having means for hose connection, and the valvecasing 2is also provided with the usual inlet 8, 'which is connected to thesupply-main.

Surrounding the barrel of the hydrant is a jacket 9, extending below thesurface of the ground, as designated by numeral 10, and having a base11. This jacket is provided with a casing 12, hinged thereto at 13,Fig.2, and secured by any suitable means 14, and inclosed by thiscasing is a hand-pump 15, rigidly secured to the barrel 1 by braces 1616.

Below the main valve 4 and exterior of the valve-casing 2 is attached adrip-pot or drainreceptacle 18, around which and the valvecasing extendsbraces or connections 17 17. This receptacle may be of any practical anddesired form to receive, through fpipe 19, the water remaining in thebarrel 1 a ter the closing ci the valve 4. A ipe 20 is attached to theside of the barrel 1 one or more braces 2] and at its upper enti hasconnection by pipe 22 with the pump and at its lower end with thedrain-receptacle by pipe 23, the former connection being made bydrain-cock 24 and the latter by a union 25.

It will be observed that the jacket 9 is cut out, as at 26, to ermit thepipe connection 2G to pass therethrough from the pipe 20 to the pump 15,and this opening permits access to the stop drain-cock 24 aforementionedand also to the steam-hose-cap connection 27 of the pipe 20.

The pump 15 1s provided with the iston 28 and check-valves 29 and 30,the va ve 29 serving as a means for preventing backiovv in the pipe 22and the check 30 permitting the water to escape to the pump-casing analso ermitting a suction therein. The said checll 30 seats over adischarge-opening 31, formed in the lower portion of the casing. (SeeFig. 3.)

The operation of the invention is as foilows: In the common type ofhydrant upon the closing of the vaive the Water thereabove having norassureV remains in the barrel, Where it is iable in cold Weather tofreeze; but in this invention the accumulated water drains through thepipe 19 into the receptacle 18, from which it is drawn, throu hpipe 20,(cock 24 being open,) by the han -pump 15, accessible by the opening ofcasing 12. In case any moisture remains in the parts, as through neglectof thorough removal, a steam-pipe from any source, such as a steamre-engine, is attached to the connection 27, (the valve 24 preferablybeing closed,) and the steam so admitted forces its Way through thepipe, receptacie, barrel, and outlet 7, thawing all frozen parte andpermitting immediate use of the hydrant.

It will of course be understood that varions changes may be made Withoutdeparting from the scope and spirit of the invention.

Having fully described my invention, what i claim as new and useful, anddesire to secure by Letters Patent, is-M 1. In combination 'with ahydrant, of a drain-receptacle therefor, means for removing the contentsfrom said receptacle, and means for passing steam through saidreceptacle and thence through said hydrant.
